A sample.
High albedo roof pavers.
By using an elevated paver system water is channeled away from the roof surface reclaiming lost space.
Single ply membranes are pre fabricated sheets rolled onto the roof and attached with mechanical fasteners adhered with chemical adhesives or held in place with ballast gravel stones or pavers.
Roof ballast slabs offer the strength durability and beauty of natural stone with the potential for time and cost savings because of their ease of installation.
Designers can choose from a variety of colours textures patterns and sizes to create a unique outdoor environment.
In contrast the concrete and interlocking concrete paver pavements generally have a higher albedo and give a lower pavement temperature since more incident solar radiation is reflected from the surface 41 49.
How they can be made cool.
Pedestal systems effectively draining water from a roof or plaza is a critical issue for every building.
High albedo concrete is a special type of pavement that reflects more light than dark colored materials due to its lighter color.
This causes the concrete to maintain a lower surface temperature resulting in less energy needed to cool buildings and less energy consumed by nighttime lighting not to mention reducing the heat island effect found on many asphalt parking lots in the summer.
By preventing a majority of the heat from ever reaching the surface these roofs work to greatly reduce hvac cooling costs during the summer months.
Following the simulation results show that cool walls with an albedo rating of 0 9 showed very similar temperature reductions as that of high albedo cool roofs.
As one would expect albedo roofs are formulated with special high eminence materials that keep project a high level of thermal energy back into the atmosphere.
In los angeles the average roof albedo is about 0 17.
On a sunny day a roof that strongly reflects sunlight can stay much cooler than a roof that absorbs sunlight.
This concrete characteristic is particularly noteworthy in comparison to alternatives for paving and roofing.
A sample cool roof.
Reformulate or coat black membranes to make them reflective.
This roof has a high albedo and reflects about 63 of the energy from sunlight.
Roof ballast slabs are suitable for.
Slabs are precision fit with a consistent thickness and a slip resistant finish.
Studies have shown that concrete s reflectivity can lower lighting costs by as much as 30 over other pavements.
The cool wall had a temperature reduction of 0 054 k 0 1 albedo whereas the cool roof had a reduction of 0 059 k 0 1 albedo.
Concrete s high albedo means more light is reflected and less heat is absorbed resulting in cooler communities.
